Chopped strand mat, in fabric form, is sold on the roll and in small folded packages.
The texture of the chopped strand mat is quite rough given its random fibers (many of which come loose when epoxy is applied).
The random oriented strands are held together with light stitching, which runs parallel to the length of the roll and is spaced about 3/16" to 1/4" apart over the width of the roll.

 Epoxy Systems - Laminating - Frequently Asked Questions
Firstly CSM is used to reinforce the resin in GRP structure, where the resin usually makes up two thirds of the GRP and takes as much of the load as the glass fibre.
The primarily role of the epoxy is to hold the fibres in place and transfer the load evenly across the fibres, which bear the majority of the load.
The open nature of CSM means that it is very difficult to achieve a high fibre volume fraction.

 Other Fabrics used in Polymeric Composite Materials
Chopped strand mat (CSM) is a non-woven material which, as its name implies, consists of randomly oriented chopped strands of glass which are held together — for marine applications - by a PVA emulsion or a powder binder.
Despite the fact that PVA imparts superior draping handling and wetting out characteristics users in a marine environment should be wary of its use as it is affected by moisture and can lead to osmosis like blisters.
Today, chopped strand mat is rarely used in high performance composite components as it is impossible to produce a laminate with a high fibre content and, by definition, a high strength-to-weight ratio.
